A 22 year old former bike gang member who decides he wants to teach high school, for the high school girls.

Origin

Becoming a teacher...

Eikichi is a 22-year old former bike gang member. One day while peeping at girl's panties, a high school girl would approach Onizuka and ask him on a date. Being filled with raging hormones and still a virgin, he accepts. Eventually when they went to a love hotel, the girl would reunite with her boyfriend, who is an old, balding, high school teacher. This gives Onizuka a epiphany, that old balding guy could've been Onizuka himself. He would eventually be able to get a job as a student teacher at a public high school. There, he would inherit the worst class in the school, filled with many deliquients. However, Onizuka would eventually notice a pretty girl, and the only one, named Nanako Mizuki sitting in his class. One day, while walking home in the evening Nanako confronts Onizuka as she shedded tears. Onizuka brought her in and Nanako begins to tell him about how her parents are distant now, making her depressed. Nanako would try to seduce Onizuka, as he was resisting very hard, a few of the deliquients jumped in and took photos of Onizuka with Nanako on top of him, black mailing him to either leave or pay one million yen. Onizuka was unable to do anything, as he was still a teacher and laying a hand on the kids would result in legal actions.

The deliquients would decide to hang out in the park, near some bikers. After they told the bikers to shut up, the bikers took offense and started approaching the high schoolers. However, Onizuka comes from the back of the crowd, knocking all the bikers in his way down. Eventually he gets to the leader, where just the mention of his name caused all the bikers to follow Onizuka. As the students thought Onizuka was there to save them, Onizuka decides to just torture them for what they did to him. And threatens them, that if he can't get a teaching job, it will be their fault. The very next day, Onizuka was hanging out with his friend Ryuji before his class started, and he was sulking as he regreted torturing those kids. However, to his surprise, all the students in the class decided to become obediant. Nanako would confront Onizuka after class, eventually Onizuka would learn that everything she told him before was true, and after Nanako almost killed herself jumping off Onizuka's bike, he decided to go to her parent's house and set things straight. He waltzes in the house, and goes into her dad's room with a sludge hammer, and proceeds with knocking the wall down to open a hole in her dad's room and her mom's room.The next day, which is also Onizuka's last day as a student teacher, he recieves a note from Nanako about how her and her family are starting to be a family again. This gives Onizuka another goal as a teacher, and it's to help students with personal problems.

Personality

Being a 22-year old virgin, all he can think about are girls with his perverted mind. He's lazy and would often drift off in his own mind, dreaming of possible wives that barely wear any clothing. Onizuka also has a short temper, as he was a former bike gang member, he used to mainly solve many of his problems through violence. However, after becoming a student teacher, he was able to put his crazed sex drive away to help out his student's personal problems. Once he became the teacher of class 3-4, things don't get any better as he is forced to hold his temper in while the class tortures him. While teaching class 3-4, Onizuka would begin to mature as he constantly helped his students with personal problems, and winning the hearts of his students who all were in the same classes before and were betrayed by their very own home room teacher.

Live Action Onizuka

Great Teacher Onizuka was adapted into a 12 episode live action TV series. Eikichi Onizuka was portrayed by Takashi Sorimachi. It dealt with Onizuka helping his students from class 3-4 with personal problems. There were many changes in the live action series compared to the anime and manga such as main story, character development and problems, and live action only characters, but it was able to capture the feel of the original Great Teacher Onizuka.
